That happens if I try to play the video.

I'm using Fedora 41 KDE (Wayland) and created a screen recording with spectacle. Then I tried to play the video and while Dragon Player opens, it doesn't play it. I created a short video of it. I can't even play this video with DragonPlayer.

I had a look into 'journalctl -f'. I can see ten thousands of these error messages:

> dragon[355267]: QPainter::fillRect: Painter not active

But I can also see these error messages:

Hi - just a note, I don't think the repeated "QPainter::fillRect: Painter not active" errors are related to your issue, as I get those messages in my system journal as well but can play videos just fine.
